Probiotics for better bowel health
A new study on poultry, supported by BBSRC, reveals the effects of the feed additive derived from yeast on the health of the digestive system.
According to a study supported by the Biotechnology and Biological Sciences Research Council (BBSRC), the use of a probiotic yeast cascade in nutrition has positive effects on the development of young broiler broilers and the defense of animals against intestinal infections is strengthened. Reducing infectious diseases in the intestines of broiler broilers without the use of antibiotics is an important problem that needs to be overcome for the individual farms and the poultry industry, as well as for animal welfare to reduce the spread of strong bacteria to the antibiotic.
A scientist from the University of Nottingham Trent supported and observed 240 broiler chickens each day for 42 days with different doses of a yeast-based feed additive. All other conditions that the chickens are exposed to are the same except for their feeding. Scientists have found that by providing a carbohydrate-containing feed additive found in yeast, they have a stronger organic defense against harmful bacteria found in the intestines of poultry and benefit from the additive of young broiler chickens. This study carried out in partnership with the private sector and the scientific platform was carried out in order to eliminate the questions about the mechanism of action of the feed additive used in broiler breeding.
Increased mucin secretion
Researcher Harriet Lea said that in the UK, 184 million broiler chickens suffer from digestive-related diseases each year, which in turn adversely affects animal welfare and growth. Noting that there are many non-natural feed additives in the market, Lea said that these things need to understand exactly how they support digestive health in poultry, and that breeders have a better chance to improve efficiency and improve herd health. This will help address antibiotic resistance, which is a serious issue in poultry, and will be a useful move to reduce the need for expensive antibiotic therapy. In the study published in the Journal of Applied Animal Nutrition, the benefits of a feed additive belonging to a company were demonstrated and it was stated that the storage capacity of mucin, which helps to defend against a substance secreted from the intestinal surface and infectious agents, may be related to age in young birds.
The natural carbohydrate fraction studied was, in fact, a feed supplement used in some commercial broiler diets, but there was uncertainty about how it worked. Although the additive was able to work with a variety of mechanisms, the findings helped explain how the additive improved the immune system in poultry with modified mucin production. These new findings may lead to a wider use of feed additives derived from yeast to improve digestive health and immunity in broiler feeding. The next stage of the project is to explore the effects of this organic carbohydrate fraction on poultry gene expression in order to investigate whether the feed additive promotes changes in poultry development and digestive health at a molecular level.
